APPARATUS FOR THE RECORD AND REPRODUCTION OF SOUNDS.

SPECIFICATION forming part of Letters Patent No. 409,004, dated August 13, 1889.

Application filed April 13, 1889. Serial No., 307,087. (No model.)

To all whom it may concern:.

Be it known that I, GIANNI BETTINI, a subject of the King of Italy, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Means for the Record and Reproduction of Sounds; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.

- This invention relates to the record and reproduction. of sound, or to graphophony.

The object of the invention is to produce means whereby articulate speech and other sound or sounds may be recorded and reproduced with great amplitude and distinctness.

Vith these objects in view the invention resides in an apparatus comprising a diaphragm or other body capable of vibrating and a conductor of vibrations bearing upon or attached to several points of the diaphragm or other vibrating body and converging to a common or central point or place, at which point 01' place is placed a projection or wheel designed to make a record or to traverse a record already made and communicate the vibrations from such record to several points of a diaphragm or other vibrating body.

By experiment it has been ascertained that when by articulation or other cause of production impulses are imparted to a fiuid such as airand are conveyed to a substance capable of being vibrated the vibrations caused in the substance are practically uniformthroughout. I have found that these vibrations can be taken off at several points or places, be communicated to a common or central point or place by means of transmitters, and be impressed upon a yielding material, producing a record of the vibrations, so that when the same or similar central or common point or object communicating with several parts of a body capable of vibration is passed over the record vibrations corresponding to those originally produced are set up at several parts of the body, and, the vibrations from these parts being imparted to the air, great amplitude results, with precision of form, giving great distinctness.

In the accompanying drawings I have ill ustrated a suitable apparatus for carrying out my idea.

In the drawings, Figure 1 is an inverted plan viewof a frame or diaphragm with four converging arms or conveyers. Fig. 2 is a sectional view of the same. Fig. 3 is an inverted plan of a frame or diaphragm with the converging arms or conveyers, and showing three enlargements; and Fig. 4 is a sectional view of the same.

In the drawings, A represents a frame carried and sustained in suitable position to move longitudinally with relation to a cylinder or other body capable of receiving impressions or to be stationary with relation to a longitudinallymoving cylinder or body of this kind. The mechanism employed for moving the cylinder or other body or for moving the frame need not be herein particularly described, as the same forms no part of the present invention.

The frame contains a chamber, one side of which is formed by any suitable body capable of receiving vibrations-such as a diaphragm Bpreferably attached to the frame in such manner that a practically air-tight joint is formed. On the exposed face of the diaphragm is arranged a spider C, which has a number of arms or conveyers 0 attached to the diaphragm at several points or places and converging to a common point 0, where I place a projection with or without a small wheel, the projection being designed to receive vibrations from the diaphragm and impart them to a suitable body for making a record, and subsequently to traverse the record so made and impart the same or nearly the same vibrations to the diaphragm as those originally imparted, causing sound-waves corresponding to those originally produced.

In order more perfectly to preserve the character of the vibrations set up in the diaphragm, I find it of advantage to constructthe frame 0 of such rigid material that it has the least possible amount of independent vibration, in order that no interference with vibrations transmitted from the diaphragm to the common or central point or place shall take place. For this purpose I find that arms or 0011- veyers T-shapedin cross-section are effective. At the central or converging points of the arms I place any suitable device adapted to make the record upon a soft or yielding substance and to traverse a record, or afterward to traverse the record so made without injuring it. I find that a wheel of some substance, preferably of agate or ruby in the nature of a jewel, and to which light or sticky particles will not adhere, is particularly adapted for this purpose, as by it the disadvantage of a cutting-tool or stylus from which false vibrations are liable to be set up are avoided. By using a wheel contact may be made with a cylinder or other body directly at right angles to its axis, thereby causing more perfect and uninterrupted communication with the impression of the record. On the opposite side of the frame to that at which the diaphragm is placed I may attach a tube, and, if desired,I may attach to this tube a funnel shaped mouth or car piece.

While I have herein described the production of a record as well as the reproduction of sound or sounds therefrom by my apparatus, I desire to be understood as not wishing to limit myself in this respect, since I may employ my device with fine effects as to increased amplitude and distinctness in con- 11 eetion with any phonographic record madethat is, act upon my common or central point and from this communicate vibrations to several parts of a diaphragm.

By using apparatus constructed in accordance with my invention, wherein there are several points of contact with the diaphragm or other vibrating body, I obtain a much stronger vibration of the point making the record, as I utilize the force of all the vibrations which are found to be uniform throughout the diaphragm. Further, by having the conductor attached to several places on the diaphragm, the common or central point bearing the device for making the record or of traversing it when made is held rigidly in proper position, and any independent vibrations tending to mutilate the record are obviated.

Ilaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device for recording and reproducing, or for recording alone or reproducing alone, articulate or other sound or sounds, the following instrumentalities in combination, nanu 1y: a body capable of vibration and two or more independent conductors attached thereto capable of conveying vibrations from the body, said conductors connecting with a unitary or funetionally-single part or focus designed to make a record, substantially as described.

2. In an apparatus for recording and reproducin g, or for recording alone or reproducing alone, articulate or other sound or sounds, the following instrumentalities in combination: a body capable of vibration, two or more conductors attached to different parts of the body and capable of conveying vibrations therefrom, said conductors connecting with a functionally-single part or focus capable of making a record, and a yielding substance properly situated in relation to the single part to enable a record to be made upon such single part, substantially as described.

3. In a device for recording and reproducing, or for recording alone or reproducing alone, articulate or other sound or sounds, the following instrumentalities in combination, namely: a diaphragm capable of vibration, two or more rigid conductors suitably attached to the diaphragm and converging to a commen or central point or focus, and a projection with or without a wheel designed to make a record on a soft or yielding substance and to traverse this or any other suitable record, substantially as described.

4. In. a device for recording and reproducing, or for recording alone or reproducing alone, articulate or other sound or sounds, the following instrumcnt-alities in combination, namely: a diaphragm capable of vibration, two or more angular conductors suitably ap plied thereto capable of conveying vibrations from said diaphragm, the conductors connecting with a unitary part or focus, and a projection with or without a wheel attached to this part and designed to make a record and traverse this or other suitable record, substantially described.

5. In a device for recording and reproducing, or for recording alone or reproducing alone, articulate or other sound or sounds, the following instrumentalities in combination, to wit: a frame containing a single chamber, a diaphragm or other body capable of vibration forming one side of said chamber, two or more conductors capable of conducting vibrations attached to the diaphragm and convergin g to a unitary point or focus, a projection attached to this point, and a tube or tubes forming an inlet or an outlet for the chamher.

In testimony whereof I ailix my signature in presence of two witnesses.

GIANNI BEITINI.
